Warning Signs
Truck Entrance Ahead Sign
Trucks may enter the road from an access on the side shown by the symbol.
What to Do
Watch the entrance and leave room for a large vehicle to turn or join traffic.
A Detail to Remember
The side of the picture matters: a mirrored symbol warns of an entrance on the opposite side.
Understanding Warning Signs
Yellow warning signs ask you to anticipate a condition ahead. Read any distance or speed plaque with the main symbol, then adjust to what you can actually see on the road.
